nope, but I wish :)
you can use it for house heating.
Not necessarily some boilers are not compatible so anyone thinking of doing so check with manufacturers.
in general the quality of cars is decreasing, and I doubt that now are used more robust components. I believe in opposite and the reality confirms it. Old cars have no problems even with used oil from mcdonalds...
Again not in all cases, I was speaking in terms of the seals that are of a different composition these days to take more high octane fuels so won't perish like rubber.
so you think that manufacturers are worried to reccomend biodiesel because of oil companies? :)
And they are not worried to constantly work on decreasing the consuption with more efficient engines, aerodynamics, downsizing, start-stop systems, hybrids, energy tires...?
Only because they feel it is politically correct with the eyes of the world on them as the biggest polluter, and because they know that with fuel prices as they are they need a new edge, that's how it is.
I think that car manufacturers do not test their wehicles on biodiesel, furthemore the quality of biodiesel may by varying and the sensitivity on fuel quality of new turbodiesel engines is fact, it is the reality, not just words from somebody.
I am not surprised that car manufacturers do not reccomend it.
Nail on the head, it is because there are people who make there own and isn't controlled and they are worried about the warranty claims.
I am surprised that you have bought car for 40 grand
more like 15 grand
and now you want to save every penny with high risk. Even with high quality diesel has IS220d quite lof of problems with reliability, with price tags of new parts: EGR app 350 eur, turbo 2500 eur, DNPR 2000 eur, injector I guess about 400 eur.
The proof is that if it runs on diesel it will run on biodiesel, we just need to make sure it is good biodiesel, and in trms of economics I can fill my Lexus up for £20 rather than 60 plus and that's not going to have any effect on EGR's or DNPR's or turbos etc.
If you want to drive economically, buy old jetta 1.9d or something similar and you will have no troubles with veg oil...
No thanks
